Seth Rogen on Why He and James Franco Shouldn't Perform at Kanye's Wedding (Video)

The "Neighbors" star reveals why a live rendition of their "Bound 2" parody "might not be the best idea" and how the spoof started.

Seth Rogen confirmed what James Franco previously mentioned, that Kanye West did invite the two actors to perform a live rendition of their "Bound 2" parody at the rapper's upcoming wedding to Kim Kardashian. But after they really thought about it, it didn't seem like the best idea, the Neighbors star revealed on Thursday's Ellen DeGeneres Show.

"Me and Franco got a call. [West] said that he was thinking it may be funny if we performed it at the wedding and we came out on a motorcycle, and then we were like, 'And then what do we do?' And then we were all like, 'I don’t know!' And then we were like, 'That's probably not gonna be very funny' because [West is] like, 'Then I'm just rapping with you and James Franco on a motorcycle for five minutes,' " Rogen explained. "And thank God [we] kind of realized that it might not be the best idea. But if he wanted me there I would have been there naked, with a shirt off, however he wanted me, on a motorcycle, doing whatever he needed."

So Rogen could still show up at the rapper's nuptials, which are rumored to be taking place later this month.

Rogen also talked to DeGeneres about why he and Franco decided to make their famous parody of the video in the first place.

"We were so taken by it that we actually literally the next morning started filming our own version of it," he said as the parody played next to West's video behind him and DeGeneres. "And then we kind of realized, like, 'Oh, we can do it exactly how they did it, like literally moment for moment, shot for shot.' And then once we realized that, we kind of became obsessed with getting it perfect, like every -- even the lighting -- and like I would try to nuzzle the same way she nuzzled. And there’s a few -- we could have done it a bit better -- but it's pretty good."

After Rogen and Franco's video went viral, the two spoofed West and Kardashian again, posting a Photoshopped version of the couple's Vogue cover.

"Once you get a laugh with the joke, you kind of want to keep going with it, I guess, is the instinct," he said. "So yeah, it, you know, you're not always proud of the laughs you get, but we perpetuated it."
